It reduces it.
This is because when reactions occur the atoms 'bump into' each other. The less atoms per space (decreased concentration) the less bumping in a given period takes place, therefore creating a slower reaction.
It doesn't - the reaction rate will not change regardless of how much of that reactant is added. That's the definition of zero-order.
Decreasing the pressure on rock will allow rock to melt at lower temperature. High pressures will raise the melting point of rock.
Affects the concentration of potassium in the urine by controlling the amount of water in the urine.
Does the temperature of water affect the reaction? blobs in the bottle
The burning of fossil fuels affects the concentration of carbon dioxide in the atmosphere by increasing it.
Decreasing the reactant concentration will slow the rate of the reaction. If you use the idea of adding oxygen and hydrogen to make water and decease the amount of one, you will produce less water. It doesn't matter which reactant is less as there are just are not enough to go around.

It leads to more frequent collisions, which increase reaction rate.
It depends on the order of the reaction. If it is zero order, decreasing the reactant concentration will have NO effect on the rate. If it is 1st or 2nd order (or more), then decreasing the concentration will DECREASE the reaction rate.

The more reactant, the faster the reaction The less reactant, the slower the reaction hope that clears it up for you
Usually, increasing concentration of reactants increases the rate of reaction, but increasing concentrations of products reduces the rate of reaction. However, if one reactant is already present in large stoichiometric excess over another, increasing the concentration of that reactant may not increase the rate of reaction at all, and if the free energy of reaction is large enough in magnitude, increasing the concentration of products may not reduce the rate of reaction at all.
yes it does
-Reactant Concentration • The greater the concentration of reactants (the more particles per unit volume), the greater will be the number of effective collisions per unit time, and therefore, the reaction rate will generally increase. • For zero order reactions, however, the reaction rate is not dependent on the concentration of reactants. Increasing the reactant concentration will have no effect on the rate. -Temperature • The reaction rate will increase as the temperature of the system increases. As the temperature increases, the reactant molecules have more energy. They thus find it easier to climb the energy barrier to the reaction (the activation energy). -Solvent • The reaction rate will increase as the temperature of the system increases. As the temperature increases, the reactant molecules have more energy. They thus find it easier to climb the energy barrier to the reaction (the activation energy).
heat is treated as a reactant or a product
There are several factors that affect the rate of reaction: -The surface area available. -Temperature -Availability of catalyst. -Concentration, if a/the reactant(s) is/are solutions. -Pressure, if a/the reactants(s) is/are gases. -Reactivity of reactants. -Activation energy of the reaction.
Increasing the concentration increases the molecules' collision frequency.
